TL;DR: Early operation of the Alcator C-MOD tokamak [I.H. Hutchinson et al., 1990] is surveyed and the edge plasma shows a wealth of marfe-like phenomena, including a transition to detachment from the divertor plates with accompanying radiative divertor regions.

TL;DR: In this paper, the authors investigated the divertor and scrape-off layer of Alcator C-Mod for a wide range of plasma conditions, including low recycling, high-recycling, and detached regimes, and reversed divertor flows.

TL;DR: In this paper, a quasi-steady state with high confinement (H=2.0), high normalized beta (βN=1.5), low radiated power fraction (Pradmain/Ploss=0.3), and low effective charge (Zeff= 1.5) has been obtained in Enhanced Dα H-mode.
